How can PHP developers troubleshoot and debug issues related to form data not being correctly processed or passed in email headers?

Issue: If form data is not being correctly processed or passed in email headers, PHP developers can troubleshoot this issue by checking the form input names and values, ensuring proper encoding of special characters, and verifying the email header syntax. 

<?php
// Process form data
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];

// Encode special characters
$name = htmlspecialchars($name);
$email = htmlspecialchars($email);
$message = htmlspecialchars($message);

// Set email headers
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
$headers .= 'From: ' . $email . "\r\n";

// Send email
$to = "recipient@example.com";
$subject = "Contact Form Submission";
$mail_success = mail($to, $subject, $message, $headers);

if($mail_success){
    echo "Email sent successfully";
}else{
    echo "Failed to send email";
}
?>
